The reason why you can only poop out a little bit at a time may be caused by improper diet, anal lesions and intestinal diseases. 1. Improper diet: Stool dryness caused by drinking too little water or eating too much spicy food can lead to obstruction of defecation, and only a little can be pooped out when pooping. Or the amount of diet is very small, thus only a little bit can be pooped out each time. 2. Anal lesions: patients with multiple anal fissures will have their anus narrowed after the formation of scar contracture in the local skin of the anus, which will lead to only a little bit of stool each time. In addition, the anal sphincter spasm patients, in defecation, the anal sphincter can not relax, resulting in stool can not be completely discharged, only a little. 3. Intestinal diseases: Intestinal occupational diseases such as colon cancer and rectal polyps can cause narrowing of the intestinal lumen, which makes defecation difficult, i.e., you can only poop a little bit at a time. There are many other reasons why you can only poop a little bit at a time, so we suggest that you consult a doctor as soon as possible to complete the examination, identify the cause of the disease, and treat the symptoms. In daily life, it is advisable to drink more warm water, and strictly prohibit eating spicy, greasy and cold food, not to mention overeating, so as not to aggravate the condition.
